The groups of pairs of open.-

ings are staggered relatively to each other so that in oneposition of. the valve tube all of the hoods 13, 14 and 15' are closed off from the vacuum tube 12 as in Figures 5, 6 and 7.

Suitable characters on the dial 24 tell of these positions when the indicator 23 registers there with. .By this means when the blower16 .is g

in operation the flues and ash-pit may bes electively or simultaneously cleaned and collections of dust and loose soot removed. By

making the ash-pan & of wire screen loose ashes may be removed therefrom through the meshes. It will also be obvious that the vacuum exhauster may, in some cases, be

used to induce or stimulate the draft through the stove by exhausting through the hoods.

- rarily shutting the ash-pit off from the fire: pot. This means consists in the present in stance of a fixed grill or slotted plate or partition 31 beneaththe grate 32 of the firep'ot against'which slides on bracket guides 33 a suitable similarly slotted closure plate 36 operated by a handle 37 at the front of the stove. Ordinarily the dpenings in the fixed and sliding plates are adjusted into register as in Figure 3, butwhen the vacuum exhauster is in use the solid portions of the sliding plate close the slots in the fixed plate.

'I claim as my invention:

' 1. The combination with a stove having a fire pot and an ash pit beneath the same, of a vacuum exliauster communicating with the ash pit and means for temporarily sealing the latter from theflre pot.

2. The combination with a stove having an 7 ash pit, a smoke flue, an oven, and anoven flue eommunicating'with the smoke flue, of a vacuum exhauster communicating with the ash pit and with the bases of the oven flue and smoke flue, and means for selectively closing ofl one or all of said points of communication. V I

3. The combination with a stove having an ash pit, a smoke flue, an oven, and an oven flue communicating with the smoke flue, the ash pit running toward the rear of the stove, and the oven flue and smoke flue being being also arranged at the rear, of a vacuum exhauster embodying a conductor extending across the rear of the stove and communicating with the ash pit, the base of the stove disposed above the bottom wall and iii-spaced relation to one of the side walls whereby to form an oven flue,'a combustion chamber communicating with the ovenflue, ,i

a smoke flue disposed at one side of the oven flue and extending substantially from the bottom to the top of the latter and communieating with the same at a point adjacent'the bottom thereof, a vacuum exhauster atone side of said oven flue having a suction passage communicating with anopening in the base of the smoke flue and also communicating with an opening in the oven flue and means for selectively cuttingoil? communication between said openings and. said pass sage.

5. The combination of a stove comprising 7 bottom, side and top walls, an ovenwithin the stove disposed above the bottom wall and in spaced relation to one of the side walls whereby to form an ovenfiue, a smoke.

flue disposed at one side of the oven flue and extendingsubstantially from the bottom to the top of the latter'and having an opening adjacent its base communicating with the oven flue, an exhaust pipe at one side of the stove having inlet-openings communicating with the smoke flue and with the oven flue, a vacuum exhauster connected with said pipe and means for selectively closing said inlet openings whereby the exhauster may be connected either with the smokefluevortheoven flue. i I V 6. The combination of a stove comprising a combustion chamber, an oven, an oven flue communicating with the combustion chamber, avertically disposed smoke'flue extending from the base tothe top of the'oven flue and having an opening adjacent j' its lower end leading to the base of the oven flue, avacuum exhausterhaving a suction passage leading to the smoke flue and to the baseof the oven flue and means for cutting off communicatlon between the suction: pipe and the smoke and oven fines.
